ENVELOP-SEALING MACHINE.

' Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed May 20,1907. Serial No. 374.744.

To all whom it may concern:

Be it known that I, FRANK A. NoRRIs, a citizen of the United States, residing at Ourwensville, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in. Envelop- Sealing Machines, of which the following is a specification.

My invention relates to envelop sealing machines, for the purpose of moistening, pasting, and sealing the same; and the object thereof is to so construct the same that the envelop or other article to be pasted may be drawn and pressed against the moistening and pasting brush by a roller operated by a lever; and by the further manipulation of a second lever the envelop is carried through pressing rolls and securely pasted.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views :Figure 1 is a side elevation of the 'device; Fig. 2 is a front view,

partly in section; Fig. 3 a longitudinal section; and, Fig. 4 a view of the pasting portion of the same; Fig. 5 a cross-section of same; and, Fig. 6 a plan of moistener.

1 represents the main platform of the device; 2 supporting standards rising from the same; 35 cross-piece connecting standards at the top; and 3 and 4 pressing rolls to receive and press the envelop.

5 is a ratchet wheel; 6 a segmental rack bar working in the same; and 7 a lever to operate the rackbar.

8 is a spring to hold the rack-bar normally retracted or in its elevated position.

9 is an arm in which the lever 7 is pivoted at 10; 11 ways in which shafts 12 and 13 of the rolls are journaled and adapted to play; and 14 are blocks located above the rolls 3, and resting upon shaft 12.

15 is a bar resting in the ways 11 and adapted to play therein, said bar lying upon the blocks 14, and held againstsaid blocks by springs 16. The springs 16 are adapted to be tensioned by means of a bar 17 resting thereon, and adjustable by a thumb-screw 18.

19 are levers carrying a roll 20, said levers being pivoted at 21 to the main frame 1, and ada ted to be operated by means of a handhol 22.

23 is a moistening brush, the same being formedof two pieces 24 and 25, held together by clamps 26, the upper portion of said .together.

' for the reason that it is generally necessary to merely paste the edges or corners of the envelop to make a complete seal. These two brushes are sup orted by arms 32 extending from the main p atform.

34 is a pin to lock the ratchet 5.

The operation of the device will be apparent from the foregoing:-The envelop is first placed beneath the brushes, the hand lever 22 raised bringing roll 20 into contact with said brushes, and the envelop withdrawn thus moistening and pasting it. It is then placed between rolls 3 and 4, and the operator pressing upon lever 7 the envelo or other article is carried between the rol s and quickly and completely sealed.

Having now fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. In a sealing machine, pasting and moistening brushes, means for pressing the article against the same, pressing rolls, ad-

'justing means for the same, and a lever for manipulating the rolls.

2. A pasting machine, means for applying paste to the article, means for mo1sten1ng the article, pressing rolls, tensioning means for the rolls, a ratchet connected with one of the rolls, a rack working in said ratchet, and a spring to normally hold the rack retracted.

3. A sealing and pasting machine, brushes to moisten and paste the article, channels formed in the rear of the brushes toreceive the fluids, a leveroperated roll adapted to press the article against the brushes, pressing rolls, ways in which the shafts of said rolls play, blocks resting upon the shaft of the upper roll, a bar located in the ways and resting upon the blocks, springs resting upon the bar, and a second bar resting upon the springs and having adjusting means to ten sion it with relation to the springs. In testimony whereof I afliX my signature in presence of two witnesses.
